Can You Find Crystals In Rocks? A Prospector's Guide

Can You Find Crystals In Rocks? Absolutely! At rockscapes.net, we know the thrill of discovering a sparkling crystal within an ordinary-looking rock. Whether you’re a seasoned rockhound or just starting, knowing where and how to look can dramatically increase your chances of success. We’ll explore proven techniques to locate these hidden treasures, focusing on understanding geological formations, identifying telltale signs, and employing effective digging strategies.

1. What Exactly Are Crystals and Where Do They Form?

Crystals are naturally occurring solids formed through geological processes, with atoms arranged in a highly ordered, repeating microscopic structure.

Crystals aren’t just pretty; they are the result of specific geological conditions. They typically form in environments where minerals can slowly precipitate out of solutions, such as hydrothermal vents, or during the cooling of magma. Understanding these formation processes helps you pinpoint locations where crystals are more likely to be found. The type of host rock, like granite, and the presence of other minerals, such as quartz and feldspar, can also provide clues. For example, research from Arizona State University’s School of Earth and Space Exploration indicates that pegmatites, a type of igneous rock, are prime locations for finding a variety of crystals due to their unique cooling process that allows for larger crystal growth.

1.1 What Geological Conditions Favor Crystal Formation?

Crystals form under specific geological conditions. These include the right temperature, pressure, and chemical environment. Slow cooling or evaporation allows atoms to arrange themselves into repeating patterns.

Hydrothermal Activity: Hot, mineral-rich fluids circulate through cracks in rocks, depositing crystals as they cool.
Magmatic Processes: As magma cools, minerals crystallize at different temperatures, forming crystals within igneous rocks.
Sedimentary Environments: Evaporation of mineral-rich water in lakes and seas can lead to crystal formation, such as gypsum and halite.
Metamorphic Processes: Changes in temperature and pressure can cause existing minerals to recrystallize into new crystal forms.

1.2 What Types of Rocks Are Most Likely to Contain Crystals?

Certain rock types are more prone to hosting crystals due to their formation processes and mineral composition.

Pegmatites: These are coarse-grained igneous rocks often containing large crystals of quartz, feldspar, and mica. They’re known for hosting valuable crystals like tourmaline, beryl, and topaz.
Granites: While typically fine-grained, granites can contain pockets or vugs where crystals like quartz, smoky quartz, and feldspar can grow.
Volcanic Rocks: Vesicular volcanic rocks like basalts and rhyolites can contain cavities filled with crystals like amethyst, quartz, and zeolites.
Sedimentary Rocks: Certain sedimentary rocks, like geodes and concretions, can contain crystal-lined interiors, often with quartz, calcite, or celestite crystals.
Metamorphic Rocks: Schists and gneisses, formed under high pressure and temperature, can contain crystals like garnet, staurolite, and kyanite.

2. What are the Best Techniques for Prospecting Crystals?

There are several techniques you can use to find crystals, each with its own advantages. Combining these methods can significantly improve your chances of finding crystals.

2.1 How to Search Tailings Piles for Crystals?

Searching through tailings piles, the discarded rock from previous digs, can be surprisingly fruitful. Other prospectors may have overlooked crystals due to mud coatings, imperfections, or simply not recognizing their value.

Tips for Prospecting Tailings Piles:

Look for Flat Sides: Train your eyes to spot any rock with flat, shiny surfaces, which can indicate a crystal face.
Change Your Perspective: Get down close to the ground to view the pile from different angles, revealing crystals you might have missed while standing.
Check for Color: Some crystals are coated with iron-based minerals, giving them a rusty appearance. Don’t dismiss these!
Poke Around the Edges: Explore the sides of the hole to see if the previous prospector left part of a pocket.
Look for Float: Search for loose crystals that may have weathered out of the pocket.
Dig Through the Pile: Crystals can be partially buried, so dig through the tailings to uncover hidden treasures.
Study the Dig: Analyze the types of rocks the previous prospector was pulling out to identify potential signs of crystal-bearing formations.

2.2 How to Follow Float to Find Crystals?

Float refers to rocks or crystals that have weathered out of their original location and been moved by natural forces. Following float involves tracking these displaced pieces back to their source, which could be a crystal pocket.

Understanding Float Movement:

Glacial Movement: Glaciers can break and round crystals, moving them long distances with no clear correlation to their origin. However, sometimes pockets are moved relatively intact, creating concentrations of worn crystals in a small area.
Wind and Water Erosion: These forces erode crystals from their original seams or pockets, displacing them downhill or radially.
Buried Float: Remember that float is often buried beneath the topsoil layer, at the boundary between the organic matter and the gravel layers.

Tips for Following Float:

Dig Test Holes: When you find promising signs on the ground, dig test holes deep enough to reach the boundary layer between the topsoil and gravel.
Explore the Area: Dig an area several feet in diameter around the initial find, expanding your search uphill and to the sides.
Follow the Signs: Track the float in the direction it leads, typically uphill, towards the potential source.
Look for Pegmatite Outcroppings: Continue digging to see if the signs of a pegmatite formation persist underground.

Identifying Good Signs for Following Float:

Flat Sides: Look for rocks with flat surfaces, indicating they had room to crystallize in a crack or pocket.
Quartz: Pegmatites are composed of quartz, so look for chunks of quartz, either alone or mixed with microcline/feldspar.
Microcline: This mineral, or amazonite, is another good indicator of pegmatite formations.
Graphic Granite: This is granite where the crystal sizes of quartz and feldspar increase together, suggesting proximity to a pocket.
Combinations of the Above: Finding a mix of these minerals indicates that the necessary components of a pegmatite seam are present.
Crystals: Discovering whole crystals or crystal fragments is a clear sign you’re close to the source.

2.3 How to Prospect Pegmatites Directly?

The ultimate goal of crystal prospecting is to find crystal pockets directly within pegmatite formations. This requires understanding pegmatite geology and recognizing the signs of potential pocket locations.

Understanding Pegmatites:

Pegmatites as Flows: Think of pegmatites as lava flows of harder rock with high concentrations of sought-after minerals.
Straight Trends: Pegmatites often extend in a somewhat straight line across or into hillsides.
Mineralized Fluid: Pegmatites are formed by mineralized fluid flowing through cracks in rocks, crystallizing in open spaces.
Pocket Patterns: Pegmatites can open up into crystal pockets, pinch out, and then open up again along their length.

Tips for Prospecting Pegmatites:

Follow Gravel Boundaries: Pegmatites are often surrounded by gravel or dirt, indicating the decomposition of surrounding rock.
Dig into Solid Masses: Be prepared to dig into solid rock, using pry bars, chisels, and sledgehammers to extract large pieces of pegmatite.
Follow Seams: Look for seams sandwiched between granite plates, as these can lead to small pockets of crystals.

Geological Indicators:

Fault Intersections: Pockets are often found where pegmatites intersect with faults.
Pegmatite Bends: Pockets can form where pegmatites bend, creating eddies during the liquid phase.

2.4 Can Dowsing Rods Help Find Crystals?

Some prospectors use dowsing rods, L-shaped metal rods held loosely in each hand. The theory is that the rods will move when the user walks over an area with crystals. While not scientifically proven, some individuals report success with this method. If you’re curious, research the technique and give it a try.
